Lately, Sumitomo Metal Mining Co., Ltd. (SMM) has teamed up with a research team from Tohoku University’s Institute of Multidisciplinary Research for Advanced Materials (IMRAM) headed by Professor Masato Kakihana, to successfully develop a new silicon-containing oxide-based red phosphor for use in white LEDs. The new phosphor is less expensively than earlier red phosphors and is expected to contribute to higher performance in white LEDs as sources of illumination. The collaborative R&D program succeeded in developing the first oxide-based pho...
